Description Rob Kenna 2007-11-01 15:54:08 UTC

There is a known issue (bug #bz290821) in the device mapper which prevents
reliable use of the cluster mirror in a configuration of 3 or more legs.  This
issue has not  been seen in 2 leg mirror configurations.  Customers should wait
for the next kernel update to the 4.6 kernel before using 3 leg mirrors.

Actually this issue *has* been seen in 2 leg mirror configurations, just not as
often.

reassigning to pkennedy
